Help - can't figure out which tooth hurts

[Lou 70]

Hi,
To say I am terrified of the dentist is an understatement. The reason being I am not always responsive to anaesthetic and have felt pain on many occasions. A lot of dentists I have seen don't believe me and tell me it's all in my head however when I shoot of the chair they get a little impatient with me, others do and are sympathetic.
I am experiencing pain on the top left side of my mouth. I have a root canal with crown, then a large filling and a filling in my wisdom tooth. It does not hurt when I eat or drink. I am unable to locate the pain. I have had all the usual checks and x-rays and nothing comes up. My dentist does not want to do anything drastic until she can locate the affected tooth. The pain comes and goes, at times it's just a mild ache and others a little sharper. If it is the wisdom tooth I will have to have this removed. This has filled me with absolute fear, what if the anaesthetic doesn't work? I do have a lot of fillings, however this is down to genetics, I clean twice a day see a dentist every 6 months and have regular teeth cleaning. My teeth are cramped unfortunately. It is a family thing, my auntie who is a hygienist also has a couple of crowns and fillings she has said it is due to a high acidity.
Is there any other way of testing which tooth is the is the issue?

Electric pulp test, endo ice, x-rays, bite checks, tooth sleuth for a cracked cusp. Have you had all those?

Difficult to guess what's going on without seeing you, especially since somebody who has seen you can't figure it out

Thank you for replying, I’ve had the bite test 3 X-rays tapping and water. Had my teeth cleaned and felt nothing unusual.
